Does anybody have experience with using – or building – a mooring cradle? What I mean by this is a cradle for a boat, in this case a boat with a long, shallow keel, for use where the boat will dry out with each cycle of the tide. This is not about hauling the boat in order to do work, but about supporting the boat upright when the tide goes out, each time.
My biggest questions are to do with design for the structure itself, and what makes sure that the boat settles into the cradle correctly when the tide goes out, so that the boat does not have to be attended each time? Or is the boat lashed into the cradle, which floats, so that they float together and come down together? I've only been able to find limited material about this on the Internet, but it appears that some kind of mooring cradle arrangement was quite common in the past in some harbors in the UK and perhaps France. I'm in the Northeast US, now with a home on a bay that dries out to mud, with a tide range of about 11 feet.
I've seen photos of the lobster boats that routinely dry out in St. Martin's, New Brunswick, Canada, but that arrangement did not look appropriate for a boat with a keel…
Any and all thoughts and references welcome!
Many thanks,
